List of sub-Project in filter

Hi (on again),

It will be my last propose evolution of the day
When I create a new advanced filter in project view, and choose "is sub-project of" in filter clause, it will show only the sub-projects of the project chosen but not sub-sub Projects.



In this example, only 3 projects (in yellow) will be returned.
It should be useful to return all sub-Project (have an a value in list of operators that allow it)

Thanks !

Vincent.
